A ring-closing metathesis based synthesis of bicyclic nucleosides locked in S-type conformations by hydroxyl functionalised 3′,4′-trans linkages

A [4.3.0]bicyclic nucleoside that contains an unsaturated hydroxylated 3′,4′-trans linkage has been efficiently synthesised. Thus, from diacetone-D-glucose as the starting material, stereoselective Grignard reactions for the introduction of allyl groups,

3′,4′-trans-Linked bicyclic nucleosides locked in S-type conformations

A novel class of 3′,4′-trans-linked bicyclic nucleosides with locked S-type furanose conformations is introduced by synthesis of two model derivatives; one was obtained by cyclic ether formation and the other by ring-closing metathesis methodology.
